vented certain new and useful-Improvements 1 in Adjustments for Metallic Window Sashes and Frames, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in.

adjustments for metallic window sash and frames, and has for its object to provide means whereby metallic window-sashes maybe ad:

j ustably fitted to the metallic frames containing them. My invention consists in the peculiar construction and arrangement of parts hereinafter described and claimed and which will be more readily understood by reference to the accompanying drawings, in which Figure l is a top view of two window-sashes in place, each of which is provided with a pair of the adjustments of my invention. Fig. 2 is an enlarged top view of an adjustment embodying my invention. Fig. 3 is a side View of the same. I

My invention is designed to overcome the difficulties attendant upon fitting metallic window-sashes into metallic window-frames in such a manner as to avoid rattling and at the same time to provide against excessive friction between the sash and the frame which will interfere with the sash being readily raised or lowered. To this end I have provided the channeled member 1, which is, attached to the tops and bottoms of the windowsashes by means of the bolts 2 and which is provided with the adj usting-screw 3. A roller 4 is provided, which may be constructed of any desired material and which is mounted upon the slidingly adjustable member 5,

which is bent in the form shown-in Figs. 1 and 2, terminating in two parallel prongs, which lie upon the face of the channel 1 and are held in position by the adjusting-screw3 in such a manner that they may be readily adjusted laterally by loosening the screw 3 and tightening it when the member 5 is in the desired position.

Where it is desiredtoprevent the channeled member 1 and the screw 3 from coming in contact with the top and bottom of the frame wherein the sash is mounted,the framesufficiently' deep madam the channeled member 1.

Having thus described my invention, what I claim as new, and desire to have secured. to me by the grant of Letters Patent, is

1. A device of the class named, consisting of aroller mounted upon a pronged bearer carried by a channeled member, the channeled member being fastened horizontally on a metallic window-sash being provided with a screw adapted to hold the prongs of the bearer in position when adjusted, substantially as and for the purposes specified.

of a channeled member provided with an adjusting-screw, a roller, and a pronged mem; ber carrying the roller and adapted to be laterally adjusted and fastened within the chanscrew, the device being adapted to be fastened horizontally on a metallic window-sash, substantially as and for the purposes specified.

In testimony whereof I affix m in presence of two witnesses.
